What ground is there for complaint if. . . we are able by the grace of God to explain some [things in Scripture], while we must leave others in the hands of God. . . not only in the present world, but also in that which is to come, so that God should for ever teach, and man should for ever learn the things taught him by God? As the apostle has said on this point, that, when other things have been done away, then these three, “faith, hope, and charity, shall endure.” For faith, which has respect to our Master, endures unchangeably, assuring us that there is but one true God, and that we should truly love Him for ever, seeing that He alone is our Father; while we hope ever to be receiving more and more from God, and to learn from Him, because He is good, and possesses boundless riches, a kingdom without end, and instruction that can never be exhausted.
St. Irenaeus of Lyon, Adv. Haer. II, 28, 3 - quoted in Hans Urs von Balthasar, Dare We Hope "That All Men Be Saved"? 2nd edition (2014) chapter 8
This is a wonderful idea concerning the Beatific Vision, and a response to the often-raised (or at least often-thought) issue of "boredom in Heaven". Although we will no longer be in time, could it be that the acquisition of the knowledge of God, given its boundlessness, could entail a kind of eternal learning, that God could be forever pouring this knowledge into us? Like everything regarding eternity, we can only try our best to produce metaphors, but this one has particular appeal, I think, to those who love learning, and may on some level not understand how Heaven could really be paradise without it.
